FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] Members of the CD300 (see MIM 606786)-like (CD300L) family, such as CD300LG, are widely expressed on hematopoietic cells. All CD300L proteins are type I cell surface glycoproteins that contain a single immunoglobulin (Ig) V-like domain (Takatsu et al., 2006 [PubMed 16876123]).[supplied by OMIM, Mar 2008] PHENOTYPE: Phenotypic analysis of mice homozygous for a targeted allele indicates that this mutation shows no notable phenotype in any parameter tested.
